Of all the failures of which we have any history or knowledge, the missionary effort is the most conspicuous. The whole question has been decided here, in our own country, and conclusively settled, We have nearly exterminated the Indians, but we have converted none. From the days of John Eliot to the execution of the last Modoc, not one Indian has been the subject of irresistible grace or particular redemption. The few red men who roam the western wilderness have no thought or care concerning the five points of Calvin. They are utterly oblivious to the great and vital truths contained in the Thirty-nine Articles, the Saybrook platform, and the resolutions of the Evangelical Alliance. No Indian has ever scalped another on account of his religious belief. This of itself shows conclusively that the missionaries have had no effect.
